Relate the pH of a solution to its hydronium and hydroxyl ion concentration and its acidity or basicity brain list if your answer is good

Write the complete balanced equation for the reaction between lead (iv) oxide (pbo2) and water (h2o).

What happened to the amount of carbon dioxide in the atmosphere from 2010–2017?

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)
